| Abstract: | In maintenance of marine meteorological instruments,it is difficult on fault diagnosis and the maintenance staffs are requested with high skills,and it is not reality for specialists to work on site.Thus a portable simulator of marine meteorological instrument is developed.The hardware of the simulator is in modular design,main modules are all embedded systems based on AVR single chip computers with low power consumption;the connections among the modules are through CAN bus,and configurable according to needs.The software is designed with the expert system based on expert knowledge library and fault tree analysis,and the fault diagnosis model.The results of test show that rapid identification and precise locating for the faults can be done with the simulator;and the serviceability and maintainability of marine meteorological instruments can be improved effectively. |
